Issac Newton's Picture
Equation: = 0
x =

Enter an equation in terms of the variable x. Then enter a starting guess for the value of x. For example,to find the square root of 2 you might enter x^2-2 for the equation, and 1 as an initial guess. The value after nine iterations is returned in the x field and all the iterations can be viewed at the bottom of the page.
Use * for multiplication, / for division, and ^ for exponentiation. You can also use functions such as exp(x), ln(x), cos(x) and sin(x).
